Serial No. 747,227.

To all whom 'it may concern:

Be it known that I, FOREST G, GAUNTT, a citizen of the United States, residing at Fort lVayne, Allen county, Indiana, have invented new and useful Feeding Mechanisms, of which the following is a specification.

This invention relates to handling material at regular and uniform rates and to the driving devices therefor.

This invent-ion has utility when embodied in feeding mechanisms, especially for handling small grain, or powdered material` in the handling of which the scroll conveyor adaptation has special value.

Referring to the drawings Figure 1 is a longitudinal section'of a scroll conveyer embodiment of the invention in a feeding mechanism; Fig. 2 is a view in elevation from the right of Fig. 1 and Fig. 3 is a section on the line Illlll of Fig. 1, looking in the direction of the arrow. i

The drive wheel 1 may be actuated from any source of power to rotatethe shaft 2 mounted in the bracket 3 on the side of the hopper 4; and in the bracket 5 mounted on the opposite end of the housing 6. The end of-the shaft .-remote from the drive wheel 1, has t-he crank 7 connected by the hook link 8 to the rock lever 9 having the adjustable fulcrum block 10, movable by the hand wheel 11 to shift the block 10 along the slot 12 in the'lever 9. The fulcrum block 10 is pivotally mounted in the bracket 13 extending from the housing 6 adjacent the bracket 5. Links 14, 15, pivotally connected to the lower end of the rock lever 9, extend to the arms 16, 17 loosely mounted on the shaft 18 extending longitudinally through the housing 6. The arm 17 carries a pawl 19 falling by gravity to engage the ratchet wheel 20 mounted on the shaft 18. The arm 16 carries a pawl 21 having a counterweight Q2 at its lower end to keep it swung into engagement with the ratchet wheel 20. This variable speed intermittent grip device may effect such slow or reduced speed of continuous rotation as may be desired for the shaft 18. The housing 6 has the intake or hopper opening 4 adjacent the drive wheel 1, while adjacent its other end, the housing 6 has the discharge or outletl opening 23. The housing 6 has the semicylindrical bottom 24 throughout its length. constant Disposed in the housing 6 adjacent the downwardly tapering intake opening 4, is the upper semicircular or semicylindrical member Q5 to complete a stroke measuring section of the housing 6 adjacent the intake opening- 4. To effect stroke measuring, the double pitch rotary scroll supply conveyer .26 leads from the hopper or intake opening 4. into the' circular opening provided by thc bottom Q4 and the member 25. The rotation of this supply conveyer Q6 may be at such adjusted feed rate for the material to be handled as may be desired. Vhen driven at a slow rate, some kinds of small particle materials tend to clog and fall forward in lumps, causing the delivery from the feeding mechanism conveyer 26 not to be uniform. To overcome this difliculty` there is mounted on tbesliaft- 18 in alinement with the conveyer Q6. and in the housing 6, the sleeve 27, carrying the brackets 9.6 sustaining the ribbon scroll conveycr 29. By tapering the hopper 4 to widen downwardly as shown in Fig. 1 there is more freedom for fall of the material. This second conveyer is driven by the sprocket wheel 30 on the sleeve 9.7. The sprocket wheel 30 is actuated by the sprocket chain 31 extending from the sprocket wheel 3Q on the shaft 9. adjacent the bracket 5. Vith the intermittent grip speed reduction device driving the primary or less capacity convcyer 26, at a reduced speed rate, the direct high speed drive of the secondary beater or ribbon scroll conveyor 29, gives this second conveyer a greater capacity than the conveyer Q6, and due to its higher speed operation it is continually making` hold of the material from the conveyer 26 in small quantitiesand quickly beating it up for uniform discharge in a subdivided state at the opening Q3. Conveyer 29 is accordingly an equalizer. The feeding mechanism as above disclosed accordingly possesses exceptional utility for feeding at definite rates, especially in mixing materials, as feed, flour, etc. The hook on the link 8 permits ready cuting out of the feedv at any time, being of special value in times of emergency. Q9 allows a falling back in the" openings between it and the shaft of large quantities of the material instead of pushing the lumps forward, so that in its operation it effects a feed in a regular stream The The ribbon conveyer partition 33 in the housing 6 prevents the material from clogging the-sprocket chain drive for the ribbon 29.

lVhat is claimed and it is desired to secure by Letters Patent is:

l. A feeding mechanism comprising a housing provided with an intake opening and a discharge opening, a. first rotary scroll conveyer to eiiect stroke measuring in the intake opening of the material handled, posi tive driving means for the first conveyer, a second rotary similar ldiameter scroll conveyer adjacent the discharge opening and coaxial with the first conveyer to effect uni-- form discharge of the material handled, and higher speed driving means for the second conveyer operative during the driving of the first conveyer.

2. A feeding mechanism comprising a housing provided with intake and discharge openings, a first scroll conveyer in ing adjacent. the intake opening, -an increased angular velocity similar diameter scroll conveyer in the housing adjacent the discharge opening and in alinement with the first scroll conveyer and driving means continuously actuating said scroll conveyers.

he combination of a pair of coaxial scroll conveyers of common diameter and different capacities, the lesser capacity being disposed to deliver tothe greater capacity, positive driving means for the lesser capacity conveyer and additional continuous driv- .ing means for the greater capacity conveyer. The combination of a plurality of conveyers of common diameter and different capacities, a lesser capacity conveyer being disposed to deliver to a greater capacity conveyer, positive driving means for `the lesser capacity conveyer, and additional continuous driving means for the greater capacity conveyer.

feeding mechanism comprising a supply conveyer, in alinement therewith a ribbon beater of similar radial extent as the s upply conveyer to which said conveyer delivers, driving means for the beater, and less rate drlving means for the supply conveyer, said beater having axially disposed shaft, arms radiating therefrom bon carried by the arms and a scroll ribwhereby the. dis'- independently of the the hous-I chargefrom the supply conveyer may be subdivided for continuous uniform delivery by the beater.

6. A feeding mechanism comprising a supply conveyer, a beater of similar radial extent as the supply conveyer in alinement therewith and to which said conveyer delivers, driving means for the beater, and less speed driving means for the conveyer.

7. A feeding mechanism comprising a supply conveyer, a ribbon beater coaxial with said conveyer to which said conveyer may deliver, a positive driving device for the conveyer independent of t e operation of the ater, a cut out for the driving device whereb the supply to the beater may be change and driving means for the beater driving device for the conveyer whereby the beater may agitate and handle the entire from the conveyer even has become effective.

. 8. A feeding mechanism comprising a supply conveyer provided with a shaft, a material agitatin beater mounted on the conveyer shaft, driving means for the conveyer independent of the operation of the beater, a cut out for the conveyer whereby the supply to the beater may be changed, and drivlafter the cut out delivered quantity' lng means for the beater whereby the beater may agitate and handle the entire quantity from the conveyer even cut out has become effective.

9. A feeding mechanism comprising a supply conveyer having a shaft, a beater to which said conveyer delivers is sleeved upon said conveyer shaft, adjustable driving means for varying the speed whereby the changed, and whereby the after the beater may handle the entire delivered quan-l tity from the conveyer even after the cut out has become effective. In testimony whereof I affix my signature 1n the presence of two witnesses.
